On an Earth where neither heroes nor kaiju exist, an alien suddenly falls from the sky. This Ultra’s symbol is the red space boomerang he holds, the Omega Slugger, and his name means “ultimate.” “Omega” is an alien who has lost his memories. Taking human form and adopting the name “Sorato”, he becomes interested in the life forms called “Earthlings” that he is encountering for the first time and attempts to understand them. When a giant life form appears, amnesiac Sorato recalls a word—“kaiju”. As these kaiju continue to appear before him, a sense of duty awakens in Sorato’s subconscious. He transforms into “Ultraman Omega” and an intense, fast-paced fight unfolds. The Earthlings, in turn, are grappling with encountering these gigantic life forms and the alien that fights with a red slugger for the first time, watching from various places and trying to understand what they are. Before long, Sorato and an ordinary young man—an alien and an Earthling, become friends.

When the man suddenly takes off, Kosei's pursuit lands him right in the middle of a kaiju attack tearing through the city! Witnessing Kosei's compassion for a girl in the shelter, the amnesiac resolves to shield the city from the kaiju, and a crimson light ignites within him!
Episode 2
The amnesiac man declared his name: Omega. Kosei brought him back to the warehouse, and they start living together. Though Omega's past remained a mystery, the two ventured into the forest, hoping to uncover the true nature of the kaiju reported on the news. It was within this forest that their path crossed with Ayumu Ichido, a biologist. Kosei introduced the amnesiac to Ayumu as Sorato. The three began working together to search for the kaiju.
